  • In order to determine the effect of intravenous He-Ne laser irradiation, values of serum total cholesterol, Triglyceride, LDL-cholesterol and HDL-cholesterol were measured. Twenty three patients with hyperlipidemia who visited Gunpo Oriental Medical Center of Wonkwang University were treated with He-Ne laser irridiation and analyzed by Paired T-test of SPSS program. The following results were obtained : The serum Total cholesterol and LDL-cholesterol of patients treated with He-Ne laser irradiation showed a significant(P<0.05) decrease, and the serum Triglyceride and HDL-cholesterol of patients treated with He-Ne laser irradiation showed no significant(P<0.05) effects.

  • In whole world consciousness of environment maintenance have increased very quickly for the end of the 20th century. To use and disuse toxic substances have been controled at the field of industry. Also the field of lighting source belong to environmental control. And in the future the control will be strong. In radiational mechanism of fluorescence lamp mechanism is the worst environmental problem. In radiational mechanism of fluorescence lamp mercury is the worst environmental problem root. In the mercury free lighting source system the Xe gas lamp is one type. And the Ne:Xe mixing gas lamp improvements firing voltage of Xe gas lamp. Purpose and subject of this study are understand, efficiency, ideal of Ne:Xe plasma which mercury free lamp. Before ICP was designed, basic parameters of plasma, which are electron temperature and electron density, were measured and calculated by Langmuir probe data. Property of electron temperature and electron density were confirmed by changing ratio of Ne:Xe.

  • Pure Xe, Kr and Ne atoms and Mixures of Xe-Ne used in fluorescent induction lamps(FILs). However standard regulation of FILs is not made up until now. Therefore, the electron transport coefficients, the electron drift velocity W, the longitudinal diffusion coefficient NDL and the ionization coefficient $\alpha$/N in pure Xe, Kr, Ne gases and Xe-Ne mixtures(1:9, 5:5, 7:3) were calculated over the wide E/N range from 0.01 to 500 Td at 1 Torr by two-term approximation of the Boltzman equation.

  • The purpose of this paper is to propose a new type of NPI licensing context through French subjunctive and ne expletif. The distribution of NPIs on previous studies does not exactly correspond to negative function types. French subjunctive and ne expletif are good guidelines for reclassifying NPI licensing context. My classification is by a hierarchy of strength in negative force: overtly negative proposition > negative entailment > negative implicature. A new type of NPI licensing context is: (i) I-domain for negative implicature (ⅱ) E-domain for negative entailment and (ⅲ) overt negation.

  • 본 논문은 헤테로다인 간섭계를 이용한 레이저 진동 측정기에 대해 기술하고 있다. 상용 레이저 진동 측정기가 대부분 AOM을 이용하여 주파수 천이를 일으키는 반면, 본 연구에서는 Zeeman 안정화 He-Ne 레이저를 사용하므로써, 서로 다른 주파수를 가지는 레이저를 동시에 얻을 수 있었다. 따라서, Zeeman 안정화 He-Ne 레이저를 사용하는 진동측정기의 경우 간섭계 구성을 위해 사용되는 비용을 현저히 줄일 수 있다. 또한, AOM의 고주파 신호를 처리하기 위해서는 RE 대역의 신호처리 회로 설계가 필요하지만, Zeeman 안정화 레이저의 주파수 천이가 낮으므로, 제안된 진동측정기의 신호처리가 용이하다.(중략)

  • As it has been reported that the depolarization-induced norepinephrine (NE) release is modulated by activation of presynaptic $A_1$-adenosine heteroreceptor and various lines of evidence indicate that $A_2$-adenosine receptor also presents in hippocampus, and that the adenosine effect is magnesium dependent, the present study was undertaken to delineate the role of adenosine receptors in the modulation of hippocampal NE release. Slices from the rat hippocampus were equilibrated with $[^3H]-NE$ and the release of the labelled product, $[^3H]-NE$, was evoked by electrical stimulation (3 Hz, 5 V $cm^{-1}$, 2 ms, rectangular pulses), and the influence of various agents on the evoked tritium outflow was investigated. $N^6-cyclo-pentyladenosine$ (CPA), in concentrations ranging from 0.1 to 10 ${\mu}M$, decreased the $[^3H]-NE$ release in a dose-dependent manner without changing the basal rate of release, and these effects were significantly inhibited by 8-cyclopentyl-1,3-dipropylxanthine (DPCPX, 2 ${\mu}M$) treatment. When the magnesium concentration was reduced to 0.4 mM or completely removed, the evoked NE release increased along with decreased basal rate of release. In contrast, increasing the magnesium concentrations to 2.4 and 4 mM, decreased the evoked NE release. The CPA effects on evoked NE release were reducedby magnesium removal, but potentiated by 2.4 mM magnesium in the medium. 5-(N-cyclopropyl)-carboxamodiadenosine (CPCA, 1 & 10 ${\mu}M$), an $A_2$-agonist, decreased the evoked tritium outflow, and this effect was also abolished by DPCPX pretreatment. CGS, a powerful $A_2$-agonist, did not affect the evoked NE release. However, the effects of CPCA and CGS on evoked NE release were significantly increased by pretreatment of DPCPX in the magnesium-free medium. These results indicate that inhibitory effect of $A_1$-adenosine receptor on NE release is magnesium-dependent, and $A_2$-receptor may be present in the rat hippocampus.

  • This experiment was performed to evaluate the optimal proportion of dietary standardized ileal digestible lysine (SID Lys) to net energy (NE) proportion in growing to finishing pigs. A total of seventy-two pigs were used at phase 1 (initial body weight 37.23 ± 0.23 kilogram, for 42 d) and at phase 2 (initial body weight 54.16 ± 0.20 kilogram, for 77 d). They were arbitrarily assigned to three treatments groups consisting of four duplicates per treatment (six pigs in duplicates, respectively). Diet treatments were as follows: CON = basal diets (phase 1, crude protein (CP): 19.1%; SID Lys: 0.94%; SID Lys: NE proportion: 0.91 g/MJ / phase 2, CP: 17.0%; SID Lys: 0.84%; SID Lys: NE proportion: 0.79 g/MJ), TRT1 (phase 1, CP: 18.0%; SID Lys: 0.92%; SID Lys: NE proportion: 0.89 g/MJ / phase 2, CP: 15.8%; SID Lys: 0.8%; SID Lys: NE proportion: 0.75 g/MJ), TRT2 (phase 1, CP: 17.3%; SID Lys: 0.82%; SID Lys: NE proportion: 0.79 g/MJ / phase 2, CP: 14.8%; SID Lys: 0.7%; SID Lys: NE proportion: 0.65 g/MJ). In phase 1 and 2, growth performance did not meaningfully be affected when SID Lys: NE proportion decreased with reducing CP content. In phase 2, the nitrogen digestibility of CON group in 11 week was higher (p < 0.05) than other treatments. Also, marbling and firmness scores of TRT2 group diets increased (p < 0.05) compared with those of CON group, but dissimilarities of other meat qualities did not be detected among treatments. In conclusion, introduction of NE system can reduce negative problems introduced when dietary CP decreased. Also, 0.79 and 0.65 g/MJ of SID Lys: NE proportion is the optimal Lys: NE proportion to achieve improved pork quality without impairing the growth performance in growing-finishing pigs, respectively.

  • Objective: Despite an increasing number of investigations into the pathophysiology of necrotic enteritis (NE) disease, etiology of NE-associated diseases, and gene expression profiling of NE-affected tissues, the microRNA (miRNA) profiles of NE-affected poultry have been poorly studied. The aim of this study was to induce NE disease in the genetically disparate Fayoumi chicken lines, and to perform non-coding RNA sequencing in the intestinal mucosal layer. Methods: NE disease was induced in the Fayoumi chicken lines (M5.1 and M15.2), and non-coding RNA sequencing was performed in the intestinal mucosal layer of both NE-affected and uninfected chickens to examine the differential expression of miRNAs. Next, quantitative real-time polymerase chain reaction (real-time qPCR) was performed to further examine four miRNAs that showed the highest fold differences. Finally, bioinformatics analyses were performed to examine the four miRNAs target genes involvement in the signaling pathways, and to examine their interaction. Results: According to non-coding RNA sequencing, total 50 upregulated miRNAs and 26 downregulated miRNAs were detected in the NE-induced M5.1 chickens. While 32 upregulated miRNAs and 11 downregulated miRNAs were detected in the NE-induced M15.2 chickens. Results of real-time qPCR analysis on the four miRNAs (gga-miR-9-5p, gga-miR-20b-5p, ggamiR-196-5p, and gga-let-7d) were mostly correlated with the results of RNAseq. Overall, ggamiR-20b-5p was significantly downregulated in the NE-induced M5.1 chickens and this was associated with the upregulation of its top-ranking target gene, mitogen-activated protein kinase, kinase 2. Further bioinformatics analyses revealed that 45 of the gene targets of gga-miR-20b-5p were involved in signal transduction and immune system-related pathways, and 35 of these targets were predicted to interact with each other. Conclusion: Our study is a novel report of miRNA expression in Fayoumi chickens, and could be very useful in understanding the role of differentially expressed miRNAs in a NE disease model.
